It's time to: June
Prune dead foliage on dahlias to the ground. Use a small stake to mark the site of the dahlia and its name. Spread a layer of cow manure around. Dahlias will re-shoot in late spring.
Protect budding magnolias against possum damage with a sonic device such as Strayban.
Plant a shade tree for future pleasure and protection.
Plant tulips in the garden and in pots.
Old roses flower well in winter and it’s a great time to plant them. ‘Marechal Niel’ is a climbing tea-noisette with soft-yellow, scented blooms. ‘Safrano’
is an old tea rose with long, pointed buds opening to fragrant soft apricot.
Deep-water camellias to prolong flowering; add some seaweed to the watering can to promote plant health.
Colour the garden with annuals. Choose from pansies, snapdragons, larkspur, primrose, cineraria and alyssum.
Lift and divide summer-flowering perennials that have been left alone for a few years. Discard old, woody centres. Replant new shoots and runners from the perimeter of the clump into soil enriched with compost and manure.
